coLLAPsIBLE VEHICULAR WORK TRAILERS Filed OCT.. 9, 1950 5 Sheets-Sheet 3 INVENTOR. DAVID H. TILLEY BY United States Patent() 2,719,748 coLLAPsIBLE VEHICULAR'WORK TRAILERS vDavid H. Tilly, St. Louis County, Mo. Application october 9, 1950, Serri-tristi, 189,215 s claims. (ci. (296-24) This invention relates in general to certain new `and useful improvements in collapsible vehicular worktrailers and, more particnlarlys to a trailer adapted for use as a mobile work station for use by a crew of-men Yen.- gaged VVin applying external stone-simulative fcings to building structures.

Ln the application of stone-simulative faeings yto buildings it is necessary :to zprovide the work crew with a series of molds in which the plaster-like cement mix Ais applied Vto the building surface. This work is ordinarily carried out by making tup 'a batch of cement .and Vsand mixture in the form of a viscous paste, orvsocalled mum as it is commonly referred to in the trade. The molds, which take the form ofshallow aluminum pans', the inner faces of which are contoured .to simulateI eut stone or other masonry work, are `usually klined with a thin-Sheet of wax paper which serves thev dual function offadilirtatingseparation between themold andthe applied mud and also kof protecting the mud from sagging'or staining. lf the stone-simulative element is to be colored it desirable to sprinkle finely ground mica and other ip'owdered siliceous materials onithe face of thelpaperrbefore filling the mold with the mud In 'carrying out `this type of work a number of different sizes 'and shapes' of molds are used in order that the applied segments of stone-simulative material will be variegated verymu'eh in the manner of real stone which has been. laid into' the wall by a stone mason. v

It will be apparent that the facing of buildings with stonessir'nulative coatings, as briefly described above, lis a type of work requiring a 'highly unique set-of vtools and equipment which must be transported from the oontractors workshop .to the site -at which the jobisbeirig performed. In addition the materialsfor 'mixing' the-mud must be handy and the racks or fixtures into which the molds can be set while being filled also should be available as close as possible to `the wall which is being surfaced so as to eliminate needlessly wasted steps and` exces'sive handling.

It is, therefore, one of the primary objects of present invention to provide a vehicular ,trailerl which is uniquely constructed so as to be adapted for use by a crew of workmen as a mobile workshop in which allot the necessary tools and equipment `'for carrying out stonesimulative building facing jobs can Ibe conveyed to the work site so as to be conveniently available. It is another object ofthe present invention'to provide a vehicular trailer which can be opened up quickly and simply to provide a relatively enclosed workshop equipped with all the necessary molds for carrying ot va stonesimulative building facing job.

Itis another object of the present invention to provide a vehicular trailer of the type stated which is equipped with all the necessary materials to carry out a stonesimulative building facing job and which can be transported directly to the work so as to be located in convenient proximity thereto.

it is another `objeta ofthe present invention :to provide a Ivehicultstr trailer Aof thetype stated which is `nnitpiely 'constructed to be speeic-ally adapted for the purposes stated and which 'is furthermore 'capable of simple and edlimial' ns'tmtioll.

With the `above and other objects-in view, 'my invetr tion residesvin the novel features of form, construction, arrangement, and combination vofpaxfts presently and pointedoutin the claims.

Ytransverse channel -3 a1ong=the vextended eenterli-neof the frame 1 and are Welded to yeaeh otheriand Vto a drawbar 6 'which-extends :forwardly and rearwardly therefrom, .and is, at its rear- 'warrl end, welded to .the central portion of! the ero's's channel 3.r :At its forwardly .projecting Yend the drawbar 6- is provided with 'a Vconventional trailer-hitehiiig element 7. 1 -h Mounted upon and. extending across 'the upper face of the chassis 1` is avoor 25 vprovided with two-vertieally Yextending end Walls 26, `27, and a longitudinally -eilte'ndling back wall 28.` Hingedly' mounted tothe upper maiiof the back ewall A28 .isy artop 'fwa'll l29 wlieh extends horizontally across the trailer in upwardly spaedprlfziel relation to the `floor-fand rests', along Vits transverse margins, on the upper lhorizoi'ital 'margins' of flieend walls 26,. 27', terminatingin a longitdinal-irilargin which isv coincident'with. 'the opposite margin of the Hoor 25.v

-Rigidlyisecured to the top wall 29 a side-wall530wlileh extends. downwardly therefrom and closurewisl across :the of the trailer and in opposed parallel relation Vto the side wall It Ishould be noted thatifh trailel-"is approximately' as high as it. is wide vso that the vetie'l dimensions. rof the sidewalls 28, 30, are substantially eql tothe :width: of the ltrai-1er for purposes` presently irnore ful'ly'appearing.

-Hingedly mounted to the top Wal-l 29 and normally lieartendng.along the under' faee "thereof infinwrdlfy spaced relation to the end. walisdzs, A27', are vfront and rer iiywalls 31,31l .By referenceto Figures-l arid '2 ift ivillbe Aseen thatfwhe'n the top 'Wall 29 arid theside lii/all '13G-'dre swung. upward-ly so that the top'Wal-lf129 is iriverticl alignment with the side wall 28, the side wall 30 will extend laterally therefrom in the formation of a roof and the ily-walls 31, 32, may be swung outwardly into vertically aligned coincidence with the end walls 26, 27. It will be noted that the ily-walls to the top wall 29 in such a manner that their bottom edges will rest upon the top edges of the end walls 26,

31, 32, are hinged 27, and the top edges will rest supportingly against the under face of the roof-forming side wall 30. The ilywalls 31, 32, are furthermore provided with vertically shiftable bolts 33 which may be slid downwardly into locked engagement into keepers 34 rigidly mounted upon the inner faces of the end walls 26, 27, adjacent the upper margins thereof. When the bolts 33 are engaged in the keepers 34 the entire structure will be rigidly locked in opened position forming a sort of shed-like enclosure having a lioor, a roof, a back wall, and two side walls and being open across one face, as shown in Figures l and 2.

Disposed within the body of the trailer and extending across the side wall 28 between the end walls 26, 27, is a work table 35 located in slightly downwardly spaced relation to the top wall 29 when the trailer A is closed up. The work table 35 is provided with three recessed shallow mixing basins 36, 37, and 38 and a central supporting leg 39 which serves to reinforce the workbench ortable 35 and enable it to support a substantial load. In the area between the rearwardly disposed end wall 26 and the supporting leg 39 beneath the work table 35 is a series of spaced parallel shelves 40 and partitions 41 which, in effect, form pigeon-holes for the molds which are used in the formation of a stone-simulative building facing. In the space beneath the mixing basin it is possible to carry various drums or containers for storing the cement, coloring powder and other materials which are employed in this type of work.

Preferably, though not necessarily, the side walls 28, 30, are provided upon their outer faces with wheel enclosing fenders 42 of more or less conventional design. It will be noted in this connection that when the trailer is' opened up the fender 42 which is associated with the side wall 36 will be on top of the entire structure, as best seen in Figure 1.

Swingably mounted upon the drawbar braces 5, 6, are jack legs 43, 44, each provided with downwardly swinging ends with relatively large disc-like foot pads 45. When the trailer is opened up for use as a workshed the jack legs 43, 44, may be swung downwardly into ground engaging position, as shown in Figure 5, thereby supporting the trailer in relatively horizontal position as a stable work-platform.

It shouldlbe understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the vehicular trailers may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. A vehicular trailer comprising a wheel-mounted chassis having a oor, a forward end wall, a rearward end wall, a longitudinally extending side wall connecting the end walls along one side of the vehicle, a top wall hingedly connected to the side wall and extending ,across the upper margins of the end walls in upwardly spaced parallel relation to the bottom wall, a second side wall rigidly mounted at its upper margin to the outer margin of the top wall and extending closurewise downwardly therefrom between the end walls, said top wall and second side wall being adapted to swing upwardly as a unit so that the top wall forms a vertical upward extension for the first s ide wall and the second side wall becomes a roof-like member, wall forming end wings hingedly connected to the opposite margins of the top wall yand being adapted, vwhen the latter is disposed in closure-wise position, to fold inwardly into underlying relation with respect thereto and be also adapted to fold outwardly, when the top wall is in vertical position, into edgewise engagement with the second side wall and the upper margins of the end walls respectively for supporting the top wall and second side wall in such upwardly disposed position, and means for optionally locking the end-wings in such top-wall supporting position.
